Christian, I should clarify my earlier statements regarding error code. 
  I was referring to the typical percolation I expect to see on a newlib 
compile error.  I have an example below for mn10300-elf whereby I simply 
added a non-existent type to the file:

/home/jjohnstn/sourceware/src/newlib/libc/argz/argz_insert.c: In 
function ‘argz_insert’:

The error 1 code for lib_a-argz_insert.o from gcc is expected.  It 
should have percolated up to [all] with Error 2 unless you specified -i 
or -k.

Thanks, will check in the patch.
